“…Considering that the emergence and survival of oak seedlings is currently constrained by elevated temperatures and water shortage conditions that occur during their growing season (Alfonso-Corrado et al 2007, González-Salvatierra et al 2013, Badano et al 2015, our results indicate that climate change will magnify these effects and negatively affect these early recruitment processes of oaks. Our findings also indicate that oak seedlings subjected to higher temperatures and lower water availability can display functional responses that, despite reducing their growth, may confer them some tolerance to these climatic changes.…”

“…Nevertheless, these seedlings had lower ɸ PSII than control seedlings, which indicates that climate change may impair this light-dependent process of photosynthesis. Several authors reported that thermal and water stress impair the capability of plants to convert light into chemical energy for fixing carbon (i.e., NADPH and ATP), which ultimately reduces their growth and survival (Xu & Zhou 2006, González-Salvatierra et al 2013, Aragón-Gastélum et al 2014, Badano et al 2015. Thus, as these negative effects of warming and drought on seedlings were more pronounced in the clearing than in the forest, this may contribute to explain why their survival and growth rates were lower in the former habitat.…”

“…Seasonally dry forests originally covered more than 40 % of the American continent, but more than half of these ecosystems were converted in agricultural and grazing fields over the past four centuries (Vieira & Scariot 2006). Several of these fields are currently abandoned because of their low productivity and, although this could be perceived as an opportunity for the natural recovery of forested areas, tree seedling establishment in these habitats is constrained by elevated temperatures and low water availability (Badano et al 2015, González-Salvatierra et al 2013. Thus, forest recovery in abandoned fields could be even harder to achieve in the future because of the advance of climate change.…”

Background: Climate change will increase temperature and reduce rainfall across temperate forests of Mexico. This can alter tree establishment dynamics within forest and in neighbouring man-made clearings.Hypotheses: Climate change will reduce emergence and survival of tree seedlings, and surviving plants will display functional responses matching with these changes. These effects should be more noticeable in clearings due to the lack of canopy cover.Studied species: Quercus eduardii (Fagaceae, section Lobatae) an oak species endemic to Mexico.Study site and years of study: Tree growing season 2015-2016 (rainy season) in a mature oak forest and a neighbouring clearing in Sierra de Álvarez, state of San Luis Potosí.Methods: In both habitats, we established control plots (under current climatic conditions) and climate change simulation plots (increased temperature and reduced rainfall). At the beginning of the growing season, we sowed acorns of Q. eduardii in these plots and monitored the emergence, survival and growth of seedlings. At the end of the growing season, we assessed functional responses on surviving seedlings.Results: Seedling emergence and survival were lower in climate change plots from both habitats. However, differences in survival between climate treatments were larger within the forest. Seedlings from climate change plots displayed functional responses indicating higher levels of thermal and water stress.Conclusions: This study indicates that climate change will constrain tree recruitment in Mexican oak forests. However, contrary to our expectations, it seems that these effects will be higher within forests than in man-made clearings.

“…Besides these effects of temperature and air humidity, it is also important to note that PPFD levels in the plantation understory were almost three orders of magnitude above of those recorded within the forest, which may be linked to the wide openness of the plantation canopy. On this issue, some recent studies have shown that oak seedlings can display elevated photochemical efficiencies beneath closed forest canopies (Ibáñez et al, 2015), while elevated solar radiation cause their photoinhibition in open areas (González-Salvatierra et al, 2013). Thus, increased insolation is also likely to reduce seedling survival in the plantation.…”

“…Gómez-Aparicio et al, 2008). Thus, forest regeneration may be hampered in human matrices due to adverse microclimatic conditions for juvenile stages of trees (Duncan and Duncan, 2000;Gómez-Aparicio et al, 2008;Badano et al, 2009;González-Salvatierra et al, 2013). However, forest edges can ameliorate these unfavorable microclimatic conditions and provide more suitable microhabitats than human matrices for the establishment of tree species (Laurance et al, 1998;Davies-Colley et al, 2000;Asbjornsen et al, 2004;Guzmán-Guzmán and Williams-Linera, 2006).…”

Habitat divergence among close relatives is a common phenomenon. Studying the mechanisms behind habitat divergence is fundamental to understanding niche partitioning, species diversification, and other evolutionary processes. Recent studies found that soil microbes regulate the abundance and diversity of plant species. However, it remains unclear whether soil microbes can affect the habitat distributions of plants and drive habitat divergence. To fill in this knowledge gap, we investigated whether soil microbes might restrict habitat distributions of closely related oaks ( Quercus spp.) in eastern North America. We performed a soil inoculum experiment using two pairs of sister species (i.e., the most closely related species) that show habitat divergence: Quercus alba (local species) vs. Q. michauxii (foreign), and Q. shumardii (local) vs. Q. acerifolia (foreign). To test whether host‐specific soil microbes are responsible for habitat restriction, we investigated the impact of local sister live soil (containing soil microbes associated with local sister species) on the survival and growth of local and foreign species. Second, to test whether habitat‐specific soil microbes are responsible for habitat restriction, we examined the effect of local habitat live soil (containing soil microbes within local sister's habitats, but not directly associated with local sister species) on the seedlings of local and foreign species. We found that local sister live soil decreased the survival and biomass of foreign species' seedlings while increasing those of local species, suggesting that host‐specific soil microbes could potentially mediate habitat exclusion. In contrast, local habitat live soil did not differentially affect the survival or biomass of the local vs. foreign species. Our study indicates that soil microbes associated with one sister species can suppress the recruitment of the other host species, contributing to the habitat partitioning of close relatives. Considering the complex interactions with soil microbes is essential for understanding the habitat distributions of closely related plants.
